China Southern Power Grid Guangxi Power Grid Company maintained a Level III emergency response to low-temperature rain, snow and freezing disasters.

As of 16:00 on February 25, a total of 171 lines of 10 kV and above in Guangxi Power Grid were covered with ice. The power supply department made every effort to fight against ice and snow to ensure the safety of the power grid and reliable power supply.

　　Since this round of low-temperature rain and snow, the Guangxi power supply department has completed ice melting on 32 sub-lines.

　　The 220-kilovolt flying connection line is the direct power supply of the Guizhou-Guangzhou high-speed railway. It spans the high mountain areas of Lingui and Longsheng counties in Guilin City and is a key power supply monitoring line.

It was detected that the ice on the flying wires had reached melting conditions. On February 24, Xu Chao, manager of the Third Substation Management Office of Guangxi Guilin Power Supply Bureau of China Southern Power Grid, and his colleagues started the "DC" at the 220 kV Feihu substation 60 kilometers away from the line. "Ice melting" - operate the remote ice melting system on the computer to "melt ice" on the line with one click.

"We have transferred the electricity load to other lines for power supply in advance to ensure the normal operation of the high-speed railway and carry out line ice melting," Xu Chao said.

　　On the 25th, in the mountainous area of ​​Longshui Town, Quanzhou County, Guilin City, emergency repair personnel who came from the Bin area to support Quanzhou carried out emergency repair operations on a mountain road less than 3 meters wide.

The fault point of the line was located deep in the mountains and could not be reached by vehicles. Emergency repair personnel carried tools on their shoulders and walked for more than an hour on a slippery and steep mountain road to reach the scene.

The freezing rain turned the hands of the emergency crews red.

"The weather is cold, and freezing rain falls from time to time, forming thin ice on the surface of the pole. It is difficult to get up with ordinary foot buckles. We have made anti-slip modifications to the foot buckles to speed up the repair progress while ensuring safety." Guangxi guests from China Southern Power Grid Zhang Xifeng, deputy manager of the Luoxiu Power Supply Station of the State Power Supply Bureau, said that after emergency repairs, power supply was restored to the entire Sifangla branch line of the 10,000-volt long water line at 17:00 that day.

　　On the 24th, in Xiejiawan Village, Jianlu Village Committee, Wenqiao Town, Quanzhou County, a power supply repair team composed of more than 30 people was conducting emergency repairs.

That day was the Lantern Festival, and some villagers spontaneously sent glutinous rice balls and hot tea to the emergency repair workers.

Villager Wu Luqing said that the tree broke due to ice the night before and hit the power supply line. The power supply personnel started the generator overnight to ensure power supply, but they did not expect to come back early in the morning for repairs.

At present, the emergency repair work of the 10 kV Yangfu line fault at this operating point has been fully completed.

The operation and maintenance personnel of China Southern Power Grid Guangxi New Power Resources Power Supply Company inspected the 10 kV Huangbao line to check the ice coating of the equipment.

　　In addition to making every effort to ensure the stable operation of the main grid of the power grid, power supply personnel also went to Chetian Miao Township and other towns in Ziyuan County affected by freezing rain to conduct equipment inspections to ensure that every household uses electricity safely.

Thanks to adequate preparations before the arrival of the cold wave, although the transformers and power supply lines in the Taiwan area have been covered with ice, residents' homes are still warm and bright.

　　As of 16:00 on the 25th, China Southern Power Grid Guangxi Power Grid Company has invested a total of 4,956 personnel, 1,508 emergency repair vehicles, 10 emergency power generation vehicles, and 737 emergency generators to carry out anti-icing emergency response work.
